The weekend before last a friend of mine and myself made a trip to Gainesville, Florida, to the Butterfly Rainforest that is part of the University of Florida’s Museum of Natural History. They have butterflies from all over the world. Once a year, for two weekend mornings, they have a private workshop, put on before the public is admitted.
This is the only time they allow tripods and will put butterflies of your chose on any surrounds of your chose. It is a great photographic opportunity! Although I tend not to use a tripod with my setup, being able to have the personnel place the butterflies where I want, is terrific. My setup mostly is the Nikon D300s and Nikon 70-300VR lens with a 20mm extension tube.
Also, as a bit of added light I use an on camera SB-700, balanced fill flash settings, reduced to around -1.5 or so. For additional info on the Butterfly Rainforest follow this link, http://www.flmnh.ufl.edu/butterflies/. Below are just a few of the images I was able to get that day.
